Binding a property to a control using Windows Forms Designer

I want to bind a property to a control using Windows Forms Designer.

For example, I have this component:

class MyComponent:Component, INotifyPropertyChanged {
    public event PropertyChangedEventHandler PropertyChanged;
    private string _strProperty;
    [Bindable(true)]
    public string StrProperty {
      get{
        return _strProperty;
      }
      set {
        if (_strProperty != value) {
          _strProperty = value;
          if (PropertyChanged != null) PropertyChanged(this, new PropertyChangedEventArgs("StrProperty"));
        }
      }
    }
  }

I drag this component from the toolbox and drop it on a form. The component name is myComponent1. On the same form I have a TextBox control named textBox1.
Now I want to bind textBox1.Text property to myComponent1.StrProperty property. I know that I can write in code:

textBox1.DataBindings.Add(new Binding("Text", myComponent1, "StrProperty"));

but I want to achieve the same result using the designer. Is it possible? Should I use a BindingSource?

Since your question is 3 years old I'm not sure this applied to your version of Visual Studio at the time but for others interested now here's how you can do it:

  • select textBox1
  • expand (DataBindings) in the property grid
  • in Text, enter myComponent1 - StrProperty
  • press enter, done

Simple as that. If you check the generated designer code you'll see the new binding created as you would have done it by code.

No, you can only binding the property using code-behind in WinForm. However, you can binding data in WPF without C# code but using XAML.
